1.1.1 The nickel-iron-chromium alloys are UNS N08120, UNS N08800, UNS N08810, and UNS N08811. Alloy UNS N08800 is normally employed in service temperatures up to and including 1100 °F (593 °C). Alloys UNS N08810, N08120, and UNS N08811 are normally employed in service temperatures above 1100 °F (593 °C) where resistance to creep and rupture is required, and are annealed to develop controlled grain size for optimum properties in this temperature range.

1.1.2 Nickel-iron-chromium-tungsten alloy UNS N06674 is normally employed in service temperatures above 1100 °F (593 °C) where resistance to creep and rupture is required, and is annealed to develop optimum properties in this temperature range.

1.1.3 Nickel-chromium-molybdenum-columbium (UNS N06625) products are furnished in two grades of different heat-treated conditions:

1.1.3.1 Grade 1 (Annealed)—Material is normally employed in service temperatures up to 1100 °F (593 °C).

1.1.3.2 Grade 2 (Solution annealed)—Material is normally employed in service temperatures above 1100 °F (593 °C) where resistance to creep and rupture are required.

NOTE 1: Hot-working or reannealing may change properties significantly, depending on working history and temperatures.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
